"KI'IS DON'T LIE"
'SIMON & SIMON'
"EMERALDS ARE NOT A GIRL'S BEST FRIEND"
This episode marked the first part of a crossover with "Emeralds Are Not a Girl's Best Friend", an episode of 'Simon & Simon' which was broadcast immediately following this program.
In that episode, the Simon Brothers, with Higgins tagging along, trail con artist Catherine Hailey to the South American country of Costa Nueva, in order to retrieve the money stolen from an orphanage charity of Robin Masters'.
When it came time to present the 'Magnum P.I.' episode in syndication, a new ending was shot so that it remained self-contained. Catherine Hailey was caught at the airport before her plane could take off.
I am not sure what contingency measures were taken for the 'Simon & Simon' episode in syndication - it might not even be available in that format! - which would have an impact on how this story turns out.....
But as it stands now, subject to revision here is how it plays out for the Toobworld Dynamic:
The original crossover is the official storyline for Earth Prime-Time. However, at many points in the timeline of Toobworld, there have been many alterations to History - both large and small. Shows from 'Doctor Who', 'Primeval', 'Quantum Leap', 'Seven Days', etc. have made changes to how History has played out.
With any one of them, a temporal ripple, no matter how small, could have altered the events of this crossover.
Originally, Catherine got away by bribing a woman to pose as her on the plane to L.A. So that when the FBI was waiting for her at the airport, they got the wrong woman. And Higgins was held in custody instead. From that point, the Simon Brothers, with Higgins tagging along, followed the real Catherine to Costa Nueva and hatched a scheme to get her out of a country that had no extradition treaty with the USA.
And then the temporal alteration occurred.
Now, while Thomas Magnum was being beaten up by Catherine's bodyguard in the airport, Higgins faked a medical emergency to get the plane to remain on the runway. He personally escorted Catherine Hailey off the plane and delivered her to the Honolulu police.
With Catherine in custody, the 'Simon & Simon' episode never happened. But only in the new Toobworld created by that temporal quirk.
So that means this second meeting between the casts of 'Magnum P.I.' and 'Simon & Simon' did not occur:
